The accusations follow Google's recent release of a so-called that lists and describes requests that the search firm receives from copyright holders to remove links to sites containing infringing content.

In a blog post, Brad Buckles, executive vice president for anti-piracy at the RIAA, blasted Google for releasing what he called a "misleading" report that lacked adequate transparency.

"Google is routinely directing people to unlawful sources of content" contrary to what the report suggests, Buckles said. "If Google truly doesn't want its search results directing people to materials that violate copyright laws, more more should be done to address this problem."

The released last week includes details on all copyright-related content removal requests the company has received since July 2011.

The report showed that Google received 1,255,402 URL removal requests via its web form in the last month alone. Most of the URL removal requests have come from Microsoft or agents acting on the company's behalf.
